assignor to Application March 17, 1943, Serial No. 419,401 1 Claim. (01.51-186) This invention relates to hones, and with regard to certain morespecific features, to sharpeners for hand-stroking knives and the like.

Among the several objects of the invention may be noted the provision ofan economical hand-stroking hone, particularly for culinary and likeuses, which requires for its manufacture little critical war-timematerial; and the provision of a device of the class described which inaddition has the advantage of lightness and unbreakability. Otherobjects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations ofelements, features of construction, and arrangements of parts which willbe exemplified in the structures hereinafter described, and the scope ofthe application of which will be indicated in the following claim.

In the accompanying drawing, in which is illustrated one of variouspossible embodiments of the invention,

Fig. 1 is a side elevation of and,

Fig. 2 is an enlarged cross section taken on line 2+2 of Fig. 1.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawing.

Referring now more particularly to Fig. 1, there is shown at numeral I aone-piece stick formed with a handle 3 and a long, thin, tapered pencilextension 5. This stick is preferably turned from wood. The taperedportion 5 has straight tapering sides forming a long pencillike conicalform to the surface of which is applied adhesive I.

Wrapped around the conical pencil 5 and held thereto by the adhesive 1is a layer of emery cloth consisting preferably of a woven fabricbacking 9 on which is carried surface H. The adhesive I holds thebacking 9 to the pencil 5, and the whole forms a very smooth andtenaciously adhering abrasive surface onthe pencil. Suitable adhesivesare animal glue, casein glue, or some of the so-called plastic adhesivesnow available. Other abrasive sheets may be used for adherence to thestick I, such as emery paper or the like; also other abrasives besidesemery are useful. Emery covered sheets, particularly fabric areadvantageous, because of the toughness of the surface provided therebyand its quality of further embedding emery particles when stroked, sothat my new hone;

the intergral emery these particles remain useful for many sharpeningstrokes.

In arranging the emery cloth 9, II on the tapered pencil 5, it iswrapped on the bias, relative to the axis of the stick I, so. that thebutt joint shown at I3 is helically arranged on the conic pencil. Thisassures a perfectly smooth, solid and unwrinkled sharpening surface. Thebias is so chosen that said butt joint l3 has a very sharp angle withrespect to the axis of the stick I, thus presenting very littlecrosswise component thereover by stroking action of the knife which isbeing sharpened. Thus the stroking of knives and the like on the devicedoes not have any substantial tendency to pick up loose edges whichmight strip the emery cloth from the stick, such as might occur if thejoint '13 had a large wrapping angle. The angle between the joint I3 andthe axis of the stick is so small that the joint wraps around the stickless than a revolution throughout its length; in fact it is only aboutin the example shown. In addition the wrap of the Joint I3 isleft-handed, as indicated, so that when the device is normally held inthe left hand, and a knife is stroked onboth sides of it by the righthand, the action of the knife on the cone is practically parallel to thedirection of the joint when on the joint.

Features of the invention are that turned wooden sticks are easilyprepared in numbers and well-made abrasive sheets are'available in whichthe abrasive adheres tenaciously to the sheets. Since a firm adherencemay be obtained between the sheet as a whole and the stick, by means ofthe adhesive 1 the abrasive is not lost in the first few sharpeningstrokes as incases where emery is embedded directly in anadhesive-covered surface. In fact, stroking of a knife on the abrasivesheet instead of removing particles immediately and rendering thesurface useless as a sharpening surface, tends to embed the abrasive inthe sheet and makes the device useful for much longer periods of timethan might superficially be expected.

Other advantages are that the device has a one-piece core and involvesonly two pieces in its entirety (the core and the abrasive sheet). It islight in weight and may be dropped with impunity, which is not true offormer monolithic abrasive structures. In addition it can be stored withother culinary hardware pieces without the danger of breakage attendingmonolithic stone devices of this class. In addition, its initial cost isextremely low.

In viewof the above, it will be seen that the 2 2,s47,aso

several objects of the invention are achieved as illustrative and not ina limiting sense.

I claim: A hone comprising a one-piece circular stick forming a core, anintegral end portion or the stick being formed as a handle and theremainder as an elongate conical support, and an abrasive-covered sheetwhich itself is conically formed and adhesively attached to said conicalsupport, and having a bias arrangement with a butt Joint between itsedges. said jointbeing arranged as a helix of sharp helix angle withrespect to the axis of the stick such that irom and to end of the stickless than 360' oi the circular arc of the stick is occupied by thewrapping form 10 of said Joint.
